The PLATFFORM from a game publisher's perspective is still going to be Steam/Proton on Linux... More likely than not, it's all still mostly going to be Win32/64, but with improved Proton testing/targetting... this will be for SteamOS or Steam on other Linux distros... it's the same.

From your perspective you aren't waiting around for "completion" ... in terms of scope, most of it is built on efforts from Fedora/Redhat with enough customization to make it friendlier to gamers. Linux distros aren't like Windows, they share a lot and are largely interoperable or compatible with a few major camps.

But very little of this affects what will happen with games. Your experience with Steam on pretty much any Linux distro is likely to be as good or better than Steam on SteamOS.

Edit: to clarify, there are differences between Linux distros... but the fact is, that Steam on pretty much any modern/updated distro will be a very similar experience wether it's "SteamOS" or something else that you aren't having to wait around for. For that matter, you can put together a current AMD system with up to a 9070XT and run SteamOS today, the hardware is supported and you don't actually have to wait for it if you don't want to. You may find the experience better with a desktop distro, if you plan on using it more or as much of a desktop as game platform. And more so if you want to run a non-amd GPU.
